While Harvard’s new contactless student ID cards get high marks for the university’s forward thinking, the school’s student newspaper, The Harvard Crimson, panned the cards for creating a high frustration level. The reason? It’s hard to find the “sweet spot” on the reader that opens doors.

In addition, it was thought students would be able to open doors without removing the card from their wallets. That has led to “a great deal of pelvic thrusting” to get the card to work, notes this Crimson opinion piece.
